About this book
The Java Programming Wikibook is a shared effort in amassing a comprehensive guide of the complete Java platform — from programming advice and tutorials for the desktop computer to programming on mobile phones. The information presented in this book has been conceptualised with the combined efforts of various contributors, and anonymous editors.
The primary purpose of this book is to teach the Java programming language to an audience of beginners, but its progressive layout of tutorials increasing in complexity, it can be just as helpful for intermediate and experienced programmers. Thus, this book is meant to be used as:
- a collection of tutorials building upon one another in a progressive manner;
- a guidebook for efficient programming with the Java programming language; and,
- a comprehensive manual resource for the advanced programmer.
This book is intended to be used in conjunction with various other online resources, such as:
- the Java platform API documentation;
- the official Java website; and,
- active Java communities online, such as Java.net and JavaRanch, etc.
Who should read this book?
Every thing you would need to know to write computer programs would be explained in this book. By the time you finish reading, you will find yourself proficient enough to tackle just about anything in Java and programs written using it. This book serves as the first few stepping stones of many you would need to cross the unfriendly waters of computer programming. We have put a lot of emphasis in structuring this book in a way that lets you start programming from scratch, with Java as your preferred language of choice. This book is designed for you if any one of the following is true.
- You are relatively new to programming and have heard how easy it is to learn Java.
- You had some BASIC or Pascal in school, and have a grasp of basic programming and logic.
- You already know and have been introduced to programming in earlier versions of Java.
- You are an experienced developer and know how to program in other languages like C++, Visual Basic, Python or Ruby.
- You've heard that Java is great for web applications and web services programming.
Although this book is generally meant to be for programmers who are beginning to learn programming; it can be highly beneficial for intermediate and advanced programmers who may have missed out on some vital information. By the end of this book, you would be able to solve any complicated problem and tackle it using the best of your learned skills in Java. Once you finish, you are also encouraged to take upon ambitious programming projects of your own as you certainly would be able to do that as well.
This book assumes that the reader has no prior knowledge of programming in Java, or for that matter, any object-oriented programming language. The book makes it easier to understand development methodology as one reads through the book with practical examples and exercises at the end of each topic and module. Although, if you are a complete beginner, we would suggest that you move slowly through this book and practice each exercise at your pace.
How to use this book
This book as a reference book of the Java language and its related technologies. Its goal is to give a complete picture of Java and its technologies. While the book can be read from the beginning to end, it is also designed to have individual sections that can be read independently. To help find information quickly, navigation boxes are given in the online version for access to individual topics.
This book is divided to sections. Pages are grouped together into section topics. To make this book expandable in the future via the addition of new sections, the sections navigation-wide are independent from each other. Each section can be considered as a mini book by itself. Pages that belong to the same topic can be navigated by the links on the right hand side.
